Cheap DIY FM Antenna


I bought a used Sansui TU-217 some months ago just to have some background music in my living room, I have two questions:

1-There are 2 300 ohm and 1 75 ohm taps in the back of the unit, which one should I use ?

2-My current antenna is a piece of wire connected to the 300 ohm tap. I don't receive some station correctly so I would like to build a small antenna. Thing is I don't have space to have a 3 feet piece of wire hanging inside my living room. Also I live in an apartment so putting it in the roof is not an option.

What can I build that's small and serves the purpose ?

Thanks !!!

Thanks Prefab and Sugarbrie, I will also try that, I guess the rabbit won't mid hanging upside down behind my rack...or does the antenna need to be placed the other way round ?
I will add to my comment on amplified antennas that while I don't prefer them; in Doyle's case if his problem is the building blocking the FM signals, then an amplified antenna may be his only choice.
Sugarbrie...While what you say about the FM band being in the middle of the TV bands is correct, please note that amplified antenna, and mast-mounted RF amplifiers often have a "FM trap" filter to notch out the FM frequencies which adversely affect the TV picture.
You said CHEAP, right? I built this one with a few feet of speaker wire and a few wooden sticks glued together. Slips nicely hidden behind my entertainment unit, though it is directionally sensitive. You can also build one right on a wall by wrapping around nails... read the directions and you'll see what I mean. couple of links to same project - one has an animation that helps you visualize the design.

Gdoodle, excellent sites. Are you using one of those designs? I'd like to try my hand at making one myself. Does the cable connecting to the cubial have to be 300ohm ribbon feeder cable as well?
